Detailed Description

As used herein, a "power adapter" may be an electric energy conversion device that transmits electric energy to an electronic device, and the power adapter may have devices such as a transformer, an inductor, a capacitor, a control chip, and a circuit board, which are mainly used to convert a high voltage into a low voltage required by the electronic device to be able to operate, so that the electronic device, such as a mobile phone, a computer, a smart watch, smart glasses, and a bluetooth headset box, can normally operate. Taking a mobile phone as an example, the power adapter can convert alternating current on the socket into direct current to charge the mobile phone, so that the mobile phone can be normally used. Of course, the power adapter may also directly transmit power to operate the electronic device, and is not limited to charging the electronic device.

The present application will be described in further detail with reference to the following drawings and examples. It is to be noted that the following examples are only illustrative of the present application, and do not limit the scope of the present application. Likewise, the following examples are only some examples and not all examples of the present application, and all other examples obtained by a person of ordinary skill in the art without any inventive work are within the scope of the present application.

Reference in the specification to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the specification. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.

Referring to fig. 1 to fig. 2, fig. 1 is a schematic structural diagram of a power adapter 10 according to an embodiment of the present application, and fig. 2 is another schematic structural diagram of the power adapter 10 in fig. 1.

The power adapter 10 may be used to transfer power to the electronic device for proper operation of the electronic device. For example, the power adapter 10 may be a charging plug of a mobile phone, which may be electrically connected to the mobile phone through a patch cord, so as to convert the electric energy in the socket and then transmit the electric energy to the mobile phone, thereby implementing normal operation of the mobile phone. As shown in fig. 1 to 2, the power adapter 10 may include: box 100, mount 200, pins 300, and cover 400. The box 100 can be used to accommodate various functional devices required by the power adapter 10 to implement the corresponding functions of the power adapter 10. The mounting seat 200 may be disposed in the box 100 and may slide relative to the box 100 to slide out of the box 100. The pins 300 may be disposed on the mounting seat 200 and may be slid out of the box 100 by the mounting seat 200. The cover 400 may be hinged to the mounting seat 200 and may receive the pins 300, and the cover 400 may be further turned over with respect to the mounting seat 200 after sliding out of the box 100 with the mounting seat 200, so as to expose the pins 300 for use. With this arrangement, the case 100 can accommodate the pins 300 and the cover 400 when the pins 300 are not used, so as to reduce the size of the power adapter 10 and improve the portability of the power adapter 10.

All directional indications (such as up, down, left, right, front, and rear … …) in the embodiments of the present application are only used to explain the relative positional relationship between the components, the movement, and the like in a specific posture (as shown in the drawings), and if the specific posture is changed, the directional indication is changed accordingly. Furthermore, the terms "include" and "have," as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.

Referring to fig. 3 to 6 in conjunction with fig. 1 to 2, fig. 3 is a schematic structural view of the cartridge 100 in fig. 2, fig. 4 is a schematic structural view of the mounting seat 200 in fig. 2, fig. 5 is a partial enlarged view of a point a in fig. 1, and fig. 6 is a partial enlarged view of a point B in fig. 2.

The case 100 may be used to mount a functional device such as a circuit board, a charging interface, or a charging indicator light of the power adapter 10 and protect the aforementioned functional device. As shown in fig. 1 to 3, the case 100 may be similar in external shape to a flat rectangular parallelepiped structure, and the case 100 may be provided with an accommodating space 101 to mount the aforementioned functional devices using the accommodating space 101. Meanwhile, the box body 100 is parallel to the thickness direction X thereof, and the two opposite sides of the box body are both provided with sliding grooves 102, and the sliding grooves 102 can also communicate the accommodating space 101 with the outside of the box body 100. The mounting seat 200 may be disposed in the sliding groove 102 and may slide along the sliding groove 102 relative to the box 100 to slide out of or into the accommodating space 101. The material of the box 100 may be hard plastic, so that the box 100 has strong structural strength and can keep light weight.

Further, in order to connect the patch cord with the power adapter 10, the box 100 may further be provided with an opening (not shown) communicating with the accommodating space 101, so that the patch cord can be electrically connected with the charging interface located in the accommodating space 101 through the opening. The charging interface may be any one or a combination of multiple interfaces such as a micro-usb interface, a type-c interface, and a lightning interface, so that the power adapter 10 may be electrically connected to the electronic device through a patch cord corresponding to the interface. The opening may be specifically located in a region of the box 100 away from the mounting base 200, so as to prevent the patch cord from affecting the connection between the plug 300 on the mounting base 200 and the socket. Of course, the position of the opening may also be adjusted according to design requirements, which is not limited in this embodiment.

The mounting seat 200 may be disposed in the accommodating space 101, and the mounting seat 200 may also be disposed in the sliding groove 102 and may slide along the sliding groove 102 relative to the box body 100. As shown in fig. 4 to 6, the two opposite sides of the mounting seat 200 parallel to the thickness direction X are provided with sliding blocks 210, and the sliding blocks 210 on the two opposite sides can also be respectively disposed in the sliding slots 102 on the two opposite sides of the box body 100 and can slide along the sliding slots 102, so as to realize the sliding of the mounting seat 200 relative to the box body 100. The sliding direction Y of the slider 210 may be perpendicular to the thickness direction X, and the slider 210 may protrude from the outer surface of the box 100, so that a user may apply an acting force to the slider 210 to drive the slider 210 to slide in the sliding slot 102. Meanwhile, the surface of the slider 210 facing away from the mounting seat 200 may also be provided with a roughened design to form corresponding textures, so as to increase the friction force of the user contacting the slider 210. Alternatively, instead of sliding the mounting base 200 through the sliding block 210 and the sliding slot 102, sliding of the mounting base 200 relative to the box 100 may be realized by using a sliding rail, a sliding rod, a ball, or the like. Besides, the mounting base 200 may be driven to slide by a user applying an external force, or a driving device such as a motor may be used to drive the mounting base 200 to slide relative to the box 100.

Further, the mounting seat 200 may also be provided with a first surface 220 for mounting the pin 300, and the first surface 220 may also be perpendicular to the sliding direction Y. One end of the pin 300 may protrude from the first surface 220 for electrical connection with the socket, and the other opposite end may be located in the receiving space 101 for electrical connection with the circuit board. When the pin 300 is inserted into the socket at the end of the first surface 220, the first surface 220 may contact the outer surface of the socket. Specifically, the material of the pin 300 may be a metal with good electrical conductivity, and the outer surface of the pin 300 may be further plated with an anti-corrosion and anti-oxidation material, so as to improve the service life of the pin 300. Meanwhile, the number of the pins 300 may be two, and the two pins 300 may be disposed side by side on the first surface 220.

Further, the two opposite sides of the mounting seat 200 perpendicular to the thickness direction X are further provided with avoiding grooves 230, and the avoiding grooves 230 may also penetrate through the mounting seat 200 in the direction in which the mounting seat 200 slides out of the accommodating space 101, that is, penetrate through the first surface 220, so that the avoiding grooves 230 may be communicated with one side where the first surface 220 is located. Wherein, one side of the mounting seat 200 is provided with two avoiding grooves 230, the other opposite side of the mounting seat 200 is also provided with two avoiding grooves 230, and the avoiding grooves 230 on the two opposite sides of the mounting seat 200 can also be symmetrically arranged. As such, the avoiding groove 230 may be used to provide a avoiding space required for the cover 400 to be turned over with respect to the mounting seat 200, so that the pins 300 can be exposed outside the cover 400 after the cover 400 is turned over with respect to the mounting seat 200.

In order to realize the hinge joint between the mounting base 200 and the cover 400, a rotating shaft 240 may be further disposed on the mounting base 200. As shown in fig. 4, the rotating shaft 240 may penetrate through the mounting base 200, and opposite ends of the rotating shaft 240 may be respectively located in two avoiding grooves 230 on the same side of the mounting base 200, so that the cover 400 can be turned over relative to the mounting base 200 through the rotating shaft 240. The number of the rotating shafts 240 may be two, and the two rotating shafts 240 may be respectively located in the avoiding grooves 230 at two opposite sides of the mounting base 200.

Referring to fig. 7 to 8, fig. 7 is a partial sectional view of the power adapter 10 along v-v in fig. 1, and fig. 8 is another partial sectional view of the power adapter 10 along v-v in fig. 2.

Optionally, in order to enable the mounting seat 200 to automatically slide out of or into the accommodating space 101 within a certain range, the power adapter 10 may further be provided with a torsion spring 103 to drive the mounting seat 200 to slide by using an elastic force generated by the torsion spring 103. As shown in fig. 7 to 8, one side of the cartridge 100 in the accommodating space 101 may be provided with a first positioning post 110, and the mounting seat 200 may be provided with a connecting rod 250. One end of the connecting rod 250 may be connected to the mounting base 200, and the other end may be disposed in the sliding slot 102 and may slide along the sliding slot 102, that is, the other end of the connecting rod 250 may be equivalent to the aforementioned sliding block 210. Meanwhile, the connecting rod 250 may further be provided with a second positioning column 251. One end of the torsion spring 103 may be sleeved on the first positioning post 110, the other end may be sleeved on the second positioning post 251, and the torsion spring 103 may be in a deformed state to provide an elastic force to act on the connecting rod 250, so that the connecting rod 250 can slide relative to the box body 100 under the elastic force of the torsion spring 103.

The terms "first", "second" and "third" in this application are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or as implying a number of indicated technical features. Thus, a feature defined as "first," "second," or "third" may explicitly or implicitly include at least one of the feature.

Specifically, when the mounting seat 200 is located in the accommodating space 101, the height of the second positioning column 251 in the direction in which the mounting seat 200 slides out of the accommodating space 101 may be lower than the height of the first positioning column 110, and since the first positioning column 110 is fixed, the elastic force generated by the torsion spring 103 obliquely acts on the second positioning column 251 and can be decomposed into a first acting force F1 in the direction in which the mounting seat 200 slides into the accommodating space 101 and a second acting force F2 in the direction perpendicular to the side wall of the box body 100 where the sliding chute 102 is located. At this time, the first acting force F1 can limit the mounting seat 200 in the accommodating space 101 through the connecting rod 250, and the second acting force F2 can make the connecting rod 250 abut against the side wall of the box 100 opened with the sliding slot 102 to limit the mounting seat 200 from sliding out of the accommodating space 101.

Further, when the user pushes the mount 200 through the link 250 against the elastic force, the height of the second positioning portion 251 in the direction in which the mount 200 slides out of the accommodating space 101 may be equal to the height of the first positioning column 110, i.e., the first positioning column 110 and the second positioning column 251 may be disposed flush. The elastic force of the torsion spring 103 acting on the second positioning post 251 is perpendicular to the sidewall of the box 100 with the sliding slot 102, so that the connecting rod 250 can be pressed against the sidewall of the box 100 with the sliding slot 102. At this time, the mount 200 may be in a balanced state in which it does not slide out of the accommodating space 101 nor into the accommodating space 101.

Further, when the user continues to push the mounting seat 200 through the link 250, the balance state of the mounting seat 200 is broken, and the height of the second positioning column 251 in the direction in which the mounting seat 200 slides out of the accommodating space 101 is higher than that of the first positioning column 110. The elastic force generated by the torsion spring 103 obliquely acts on the second positioning post 251 and can be decomposed into a third acting force F3 in the direction in which the mounting base 200 slides out of the accommodating space 101 and a fourth acting force F4 in the direction perpendicular to the side wall of the box 100 with the sliding slot 102. At this time, the third acting force F3 may drive the mounting seat 200 to slide out of the accommodating space 101 through the connecting rod 250, and the fourth acting force F4 may cause the connecting rod 250 to abut against the side wall of the box 100 where the sliding slot 102 is formed, so that the mounting seat 200 slides out of the accommodating space 101 automatically. Accordingly, when the user pushes the mounting base 200 in the opposite direction, the mounting base 200 can slide into the accommodating space 101 automatically under the driving of the first force F1, and the movement process is the same as or similar to the aforementioned process in which the mounting base 200 slides out of the accommodating space 101 automatically, which is not described herein again.

Through the arrangement, the installation seat 200 can automatically slide out or into the accommodating space 101 within a certain travel range, the elastic force provided by the torsion spring 103 can also keep the installation seat 200 in a state of sliding out or into the accommodating space 101, and the probability that the installation seat 200 shakes in the sliding direction Y under the influence of external force is reduced.

Referring to fig. 9 to 10 in conjunction with fig. 2, fig. 9 is a schematic partial sectional view of the power adapter 10 of fig. 1 along vi-vi, and fig. 10 is a schematic partial sectional view of the power adapter 10 of fig. 2 along vi-vi.

The cover 400 may be hinged to the mounting base 200 and may receive the pins 300 on the first surface 220, and the cover 400 may be further turned over with respect to the mounting base 200 after sliding out of the receiving space 101, so that the pins 300 may be exposed outside the cover 400. As shown in fig. 2 and 9 to 10, the cover 400 may include: a first cover 410 and a second cover 420. The first cover 410 and the second cover 420 may be located on a side where the first surface 220 is located, and together enclose a receiving space 401, so as to receive the pin 300 by using the receiving space 401. For example, the first cover 410 may be provided with a first receiving groove 411, the second cover 420 may be provided with a second receiving groove 421, and the first receiving groove 411 and the second receiving groove 421 may communicate with each other to form the receiving space 401. Alternatively, the cover 400 may be provided with only the first cover 410, and the first cover 410 may be directly provided with the receiving space 401 to receive the pins 300 by the first cover 410. The scheme of only providing the first cover 410 may refer to an existing wireless headset box, which is not limited in this embodiment.

Further, the first cover 410 can be further sleeved on the rotating shaft 240 in the avoiding groove 230 on one side of the mounting base 200, and the second cover 420 can be further sleeved on the rotating shaft 240 in the avoiding groove 230 on the other opposite side of the mounting base 200. After the first cover 410 and the second cover 420 slide out of the accommodating space 101 under the driving of the mounting base 200, both the first cover 410 and the second cover 420 can be turned over relative to the mounting base 200 through the rotating shaft 240, so that the first cover 410 and the second cover 420 can be unfolded, and the pins 300 located in the accommodating space 401 are exposed, so that the pins 300 can be connected with the socket.

Further, the first cover 410 may have a second surface 412, the second cover 420 may have a third surface 422, the first receiving groove 411 may be opened in the second surface 412, and the second receiving groove 421 may be opened in the third surface 422. When the first cover 410 and the second cover 420 are turned over and unfolded relative to the mounting base 200, the first surface 220, the second surface 412 and the third surface 422 may be disposed in parallel. Meanwhile, in order to facilitate the contact between the first surface 220 and the outer surface of the socket, the height of the second surface 412 and the third surface 422 in the direction in which the mounting base 200 slides out of the accommodating space 101 may be lower than the height of the first surface 220, or may be flush with the first surface 220. With this arrangement, the unfolded first cover 410 and second cover 420 can not only separate the pins 300 from the fingers of the user gripping the case 100, but also enable the pins 300 to have a sufficient distance L1 in the thickness direction X from the edges of the second surface 412 and third surface 422, thereby reducing the thickness of the case 100 while satisfying the national security standards.

Accordingly, in order to enable the first cover 410 and the second cover 420 to automatically turn and unfold relative to the mounting base 200 after sliding out of the accommodating space 101, the power adapter 10 may further be provided with an elastic member 500, so as to drive the first cover 410 and the second cover 420 to turn by using the elastic force generated by the elastic member 500, which will be described below only by way of example of the automatic turning of the first cover 410. As shown in fig. 9 to 10, the elastic element 500 may be sleeved on the rotating shaft 240, and one end of the elastic element 500 may be connected to the mounting base 200, and the other end may be connected to the first cover 410, and the elastic element 500 may be in a deformed state.

When the first cover 410 and the second cover 420 are located in the accommodating space 101 and jointly enclose the accommodating space 401, the elastic force generated by the elastic member 500 can act on the first cover 410, so that the first cover 410 and the box 100 are abutted to limit the sliding of the mounting base 200. When the first cover 410 and the second cover 420 slide out of the accommodating space 101, the elastic force generated by the elastic member 500 can drive the first cover 410 to automatically turn over relative to the mounting seat 200 because there is no restriction of the box 100. Similarly, the second cover 420 can be automatically turned over in the same manner, and only two elastic members 500 are required to be disposed on the power adapter 10. In addition, the number of the elastic members 500 is not limited to two, and the number may also be four, and four elastic members 500 may be respectively disposed in the four avoiding grooves 230.

Alternatively, in addition to the automatic turning of the first cover 410 and the second cover 420 by the elastic force generated by the elastic member 500, the automatic turning of the first cover 410 and the second cover 420 may also be realized by the repulsive force generated by the magnetic member. For example, a first magnetic member may be disposed on the first surface 220 and a second magnetic member may be disposed on the second surface 412. When the first cover 410 and the second cover 420 are located in the accommodating space 101 and jointly enclose the accommodating space 401, the first magnetic member and the second magnetic member may be disposed opposite to each other and a repulsive force may be generated therebetween. At this time, the first cover 410 and the second cover 420 are not turned over with respect to the mounting seat 200 due to the restriction of the case 100. After the first cover 410 and the second cover 420 slide out of the accommodating space 101, the first cover 410 and the second cover 420 can be automatically turned over under the action of the repulsive force, so that the pins 300 can be exposed to the outside.

Alternatively, in addition to the foregoing embodiments, the elastic member 500 and the magnetic member may be used in combination. The difference from the previous embodiment is that the first magnetic member and the second magnetic member generate an attraction force, and the attraction force may be greater than the elastic force generated by the elastic member 500. Thus, the first cover 410 and the second cover 420 can be attached to each other to improve the adhesion between the two. After the first cover 410 and the second cover 420 slide out of the accommodating space 101, the first cover 410 and the second cover 420 can still be kept in a closed state. At this time, a user may apply an external force to the first cover 410 and the second cover 420 to separate the first cover 410 and the second cover 420 from each other, until the suction force between the first cover 410 and the second cover 420 is smaller than the elastic force generated by the elastic member 500, the first cover 410 and the second cover 420 may be automatically turned over with respect to the mounting base 200, so that the pins 300 located in the accommodating space 401 may be exposed.

According to the power adapter 10 provided by the embodiment of the application, the mounting base 200 is disposed in the accommodating space 101 of the box 100, and the mounting base 200 can further drive the pins 300 disposed on the mounting base 200 and the cover 400 hinged to the mounting base 200 to slide out of the accommodating space 101, so that the pins 300 and the cover 400 can be accommodated in the accommodating space 101 when not in use. The cover 400 is arranged to accommodate the pins 300, and the cover 400 can also be turned over relative to the mounting base 200 after sliding out of the accommodating space 101, so that the pins 300 can be exposed out of the cover 400 for use after sliding out of the accommodating space 101. In this way, the box 100 can accommodate the pins 300 and the cover 400 when the pins are not used, so as to reduce the volume of the power adapter 10 and improve the portability of the power adapter 10.

The above description is only a part of the embodiments of the present application, and not intended to limit the scope of the present application, and all equivalent devices or equivalent processes performed by the content of the present application and the attached drawings, or directly or indirectly applied to other related technical fields, are also included in the scope of the present application.
